SB 5100 problems

First off this modem worked fine for 6 months.....Then about 1 month ago my connection started to drop intermittently. Almost once an hr for no longer then 2 mins. I have had the cable company out twice. Both times they have remarked on how high my signal is. They added some splitters to knock down the signal but I still get dropped....help!


Here is the signal snapshot:

Downstream Value
Frequency 117000000 Hz Locked
Signal to Noise Ratio 28 dB
Power Level -7 dBmV

Frequency 26992000 Hz Ranged
Power Level 51 dBmV

Here are the logs from the 5100:

I had a similar problem once, but it happened when they had the DC Tap hooked up backwards and then added Digital Telephone in my area. If you're wired with a DC tap, try reversing the "tap" and "out" legs. You're looking for a little 2-way splitter type looking thing. Fixed my problems after half a dozen techs and a month later. Still going strong.
